action potential

A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse.

action potential

(Life Sciences & Allied Applications / Physiology) a localized change in electrical potential, from about -70 mV to +30 mV and back again, that occurs across a nerve fibre during transmission of a nerve impulse

action potential (

A momentary change in electrical potential on the surface of a neuron or muscle cell. Nerve impulses are action potentials. They either stimulate a change in polarity in another neuron or cause a muscle cell to contract.

action potential - A brief electrical signal transmitted along a nerve or muscle fiber following stimulation.
